The most recent one I found (using dbx, not valgrind) was a bug in a 
system library flushed out by me using RAII to match library allocations 
and deallocations.  With the "proper" code I got duplicate free errors 
and without it I got a memory leak!  In the end I settled for the leak 
and a bug report.
